btrfs-progs: crypto: add PCL based implementation for crc32c Copy faster implementation of crc32c from linux kernel as of 6.5-rc7 (x86_64, arch/x86/crypto/crc32c-pcl-intel-asm_64.S). This needs assembler build support, so detect target architecture so cross-compilation still works. Add a special CPU flag so the old and new implementations can be benchmarked and verified separately. Sample benchmark: CPU flags: 0x1ff CPU features: SSE2 SSSE3 SSE41 SSE42 SHA AVX AVX2 CRC32C_PCL Block size: 4096 Iterations: 1000000 Implementation: builtin Units: CPU cycles NULL-NOP: cycles: 77177218, cycles/i 77 NULL-MEMCPY: cycles: 226313072, cycles/i 226, 62133.395 MiB/s CRC32C-ref: cycles: 24418596066, cycles/i 24418, 575.859 MiB/s CRC32C-NI: cycles: 1188335920, cycles/i 1188, 11833.073 MiB/s CRC32C-PCL: cycles: 463193456, cycles/i 463, 30358.037 MiB/s XXHASH: cycles: 851606646, cycles/i 851, 16511.916 MiB/s SHA256-ref: cycles: 74476234956, cycles/i 74476, 188.808 MiB/s SHA256-NI: cycles: 34198637428, cycles/i 34198, 411.177 MiB/s BLAKE2-ref: cycles: 14761411664, cycles/i 14761, 952.597 MiB/s BLAKE2-SSE2: cycles: 18101896796, cycles/i 18101, 776.807 MiB/s BLAKE2-SSE41: cycles: 12599091062, cycles/i 12599, 1116.087 MiB/s BLAKE2-AVX2: cycles: 9668247506, cycles/i 9668, 1454.418 MiB/s The new implementation is about 2.5x faster.

btrfs-progs: add uClibc-ng compatibility for printf format %pV Commit [1] 164bc10d "btrfs-progs: add musl compatibility for printf format %pV" added a logic to detect the presence of the glibc <printf.h> header, and if present, to use the register_printf_specifier() and register_printf_modifier() functions. The original intent (as the commit log suggests), was to support the musl libc, which does not provides this <printf.h> header. When compiling with another libc, such as uClibc-ng, btrfs-progs fail to build with error: common/messages.c: In function 'print_va_format': common/messages.c:51:19: error: 'const struct printf_info' has no member named 'user' 51 | if (!(info->user & va_modifier)) | ^~ common/messages.c: In function 'btrfs_no_printk': common/messages.c:76:17: warning: implicit declaration of function 'register_printf_specifier'; did you mean 'register_printf_function'? [-Wimplicit-function-declaration] 76 | register_printf_specifier('V', print_va_format, | ^~~~~~~~~~~~~~~~~~~~~~~~~ | register_printf_function common/messages.c:78:31: warning: implicit declaration of function 'register_printf_modifier'; did you mean 'register_printf_function'? [-Wimplicit-function-declaration] 78 | va_modifier = register_printf_modifier(L"p"); | ^~~~~~~~~~~~~~~~~~~~~~~~ | register_printf_function This is because uClibc-ng provides a <printf.h> header, but not the register_printf_specifier() and register_printf_modifier() functions. See [2]. It mainly includes register_printf_function(). uClibc-ng emulates an older glibc behavior. Glibc added support for printf user elements in commit [3] (first included in glibc-2.10, in 2009). Checking only the <printf.h> is not sufficient. This commit fixes this build issue by refining the detection logic of the <printf.h> functions required by btrfs-progs.

I looked at the source code and found that only if ext2_fs.h defines EXT4_EPOCH_MASK btrfs-convert to support nanoseconds. But in e2fsprogs, EXT4_EPOCH_MASK was introduced in v1.43, but in some older versions, such as v1.40, e2fsprogs actually supports nanoseconds. It seems that if struct ext2_inode_large contains the i_atime_extra member, ext4 is supports nanoseconds, so I updated the logic to determine whether the current ext4 file system supports nanosecond precision. In addition, I imported some definitions to encode and decode tv_nsec (copied from e2fsprogs source code). Author: Li Zhang <zhanglikernel@gmail.com> Signed-off-by: David Sterba <dsterba@suse.com>

Use this to check inode field inclusion in debugfs instead of bare constants for inode field offsets. To fix that use the new prefixed macro and add backward compatibility that would still use inode_includes(). Issue: #785 Signed-off-by: David Sterba <dsterba@suse.com>
